Circlemark is the AI prospecting platform for commercial real estate brokers: every maturing loan, verified weekly, and the owner behind every LLC. We index every commercial mortgage in the county record — 100,000+ loans across New York City's four ACRIS boroughs and the Dallas–Fort Worth county clerks — read the maturity date from the recorded instrument itself, and keep every loan current against the record each week. Search by maturity window, size, lender, and submarket to find the loans coming due, the loans past maturity and still open, and the loans in distress or foreclosure — before anyone else does. What makes the data different is provenance. Every field traces to a citable public record — the recorded instrument, the assessor file, or a securitization disclosure — and modelled estimates are always labelled as estimates, never presented as fact. Stale data is brokers' top complaint about prospecting databases; ours is re-verified weekly. The platform includes: • Property-level loan search: lender, borrower, amount, maturity, portfolio and blanket-loan detection • Weekly lifecycle tracking: satisfied, refinanced, modified, matured-but-open, distressed, foreclosed • Owner and decision-maker contacts behind borrower LLCs, each name cited to its public record • Saved searches with weekly email digests • A Claude MCP connector — query the data in plain language inside Claude • AI-personalized outreach drafted from the loan, sent on your terms (rolling out) Live in New York City and Dallas–Fort Worth. → circlemark.ai
